Guomao ZLY280C-16-I is a two-stage cylindrical gear reducer belonging to the Guomao ZLY Series, designed for industrial speed reduction and torque transmission.

The gearbox uses a two-stage parallel shaft gear transmission system. Mechanical power from the driving motor passes through the gear stages to reduce rotational speed and increase output torque.

According to the ZLY Series designation system, ZLY identifies a two-stage cylindrical gear reducer, 280 refers to the nominal low-speed stage center distance, 16 indicates the nominal transmission ratio and I represents the assembly arrangement.

The ZLY Series uses high-strength alloy steel gears with carburized, quenched and precision-ground tooth surfaces to support high load capacity and durable industrial operation.

Typical applications include industrial conveyors, mixers, hoisting equipment, mining machinery, cement production lines, construction material machinery and mechanical power transmission systems.
